ENG CMPTR SWITCHES
Two switches, one for
each
engine, on the center switch panel labeled
ENG CMPTR CH . A/AUT0/CH . B enable the flight crew to select the
EC channel (A or B) to be used to control the engine . Normally, the
switches are left in
the
AUTO
position
which allows the EADEC
to au-
tomatically select the
most
capable channel
.
During abnormal situa-
tions, the crew may use this switch to force the desired channel to take
control of the engine .
On
aircraft 60-001 thru MAP not modified Qj SB 60-76-1 (Removal of En-
gine FADEC Reset Switch), a single ENG CMPTR RESET switch, on the
center switch panel, is used to clear malfunctions and reset the FADEC .
To reset the FADEC, the
switch is held left or right
(as
applicable) for
approximately 2 seconds . If the malfunction clears, the ENG CMPTR
light(s) will extinguish . The reset switch is not operational on the
ground . On aircraft 60-129 and subsequent and
prior aircraft modified Inj
SB 60-76-1, the ENG CMPTR RESET switch has been removed .
